The Best Over-the-Counter Eye Drops of 2025, Chosen by Eye Doctors

Why we like it: The iVizia eye drops are a favorite among ophthalmologists. These artificial tear eye drops come in a small bottle and are intended for dry eyes, but they're multipurpose and can work for just about any eye issue. Dr. Thomas Stokkermans, an optometrist and medical reviewer at All About Vision, said, "These drops have one of my preferred lubricants in it known as povidone and the high-technology dispenser has a filter in it to prevent contamination, and allows the artificial tear

AI's $344B 'Language Model' Bet Looks Fragile

Every investor knows not to put all your eggs in one basket. So why is Silicon Valley betting on just one way to build artificial intelligence? This year the world’s four largest tech firms will spend $344 billion on AI, mostly on data centers used to train and run so-called large language models (LLMs) like ChatGPT that can process text, audio and visual content. The technology is largely underpinned by the same technique of predicting tokens that appear next in a sequence.

Marines managed to get past an AI powered camera "undetected" by hiding in boxes

In what sounds like a scene from a comedy movie, a squad of Marines successfully outsmarted an advanced artificial intelligence system by employing tactics that would make any child playing hide-and-seek proud. The remarkable demonstration revealed both the impressive capabilities and surprising limitations of modern AI technology. The experiment took place as part of DARPA’s Squad X program a while back. It aimed to develop advanced surveillance systems capable of identifying human threats in

The Download: pigeons’ role in developing AI, and Native artists’ tech interpretations

People looking for precursors to artificial intelligence often point to science fiction by authors like Isaac Asimov or thought experiments like the Turing test. But an equally important, if surprising and less appreciated, forerunner is American psychologist B.F. Skinner’s research with pigeons in the middle of the 20th century. Skinner believed that association—learning, through trial and error, to link an action with a punishment or reward—was the building block of every behavior, not just

The road to artificial general intelligence

Artificial intelligence models that can discover drugs and write code still fail at puzzles a lay person can master in minutes. This phenomenon sits at the heart of the challenge of artificial general intelligence (AGI). Can today’s AI revolution produce models that rival or surpass human intelligence across all domains? If so, what underlying enablers—whether hardware, software, or the orchestration of both—would be needed to power them? Dario Amodei, co-founder of Anthropic, predicts some for

Researchers create artificial blood for on-the-spot use in accidents and combat

Forward-looking: In a laboratory at the University of Maryland, a team of researchers is tackling one of emergency medicine's most persistent challenges: how to deliver life-saving blood transfusions to patients who are miles from the nearest hospital. Their experimental solution isn't stored in a refrigerator but in the form of a lightweight powder – raising hopes among scientists and military officials that trauma care could soon reach accident scenes and battlefields alike, where blood loss r

Call of Duty cheaters complain after Activision launches new wave of mass-bans

Several players of the popular first-person shooter Call of Duty complained last week that they were permanently banned from the game for using a well-known cheat. Video game streamer ItsHapa wrote on X last week that Call of Duty players using ArtificialAiming, a cheat provider of more than 19 years, were the targets of a “massive wave of permabans,” referring to bans that cannot be reversed, which prevents cheaters from creating new accounts. The streamer also posted a series of screenshots f

Jell-O and Kool-Aid Will Soon Stop Using Artificial Dyes. Here's How to Avoid These Food Dyes Right Now

In January, the US Food and Drug Administration (FDA) banned Red Dye No. 3 in food and ingested drugs. Then, in April, Secretary of Health and Human Services Robert F. Kennedy Jr. asked that food manufacturers remove eight petroleum-based food dyes from products by the end of 2026. Now, Kraft Heinz, the company behind Jell-O and Kool-Aid, said that it plans to remove all artificial dyes from all its US products by the end of 2027, according to the Wall Street Journal. "The vast majority of our

Jell-O and Kool-Aid Will No Longer Contain Artificial Dyes. This Is What's Replacing Them.

Following the FDA's banning of Red Dye No. 3 in food and ingested drugs in January and the approval of three natural food colors in May, Secretary of Health and Human Services Robert F. Kennedy Jr. asked that food manufacturers remove eight petroleum-based food dyes from their products by the end of 2026. Now, Kraft Heinz, the company behind Jell-O and Kool-Aid, announced that it plans to remove artificial dyes from all its US products before the end of 2027, according to an exclusive with the W
